i just got a year old jungle cross from my pet shop too. It had been in the shop is october last year, so finally i broke and took him home with me. he was very snappy and came out from the hide everytime i opened the door. People say to live it for a while to adjust but i don't agree. I handled it for the first 2 hours and it bit me at least 30 times that night. When i put him back to his viv, i went back every hour to touch him which he didn't like but the next morning, he didn't mind me around. In the pet shop he wasn't handled and the viv door was opened at feeding time so he was always ready to snap his food. By handling him loads at first you will get bitten more but the calming process is cut short by much longer. They are very adaptable so don;t be afraid to handle her much. i noticed a difference in behaviour in less than 48 hours.
